Hereinafter, an operation process of the cleaner having the above-described structure will be described with reference to FIG. 4 .

When electric power is supplied to the motor 54 and the impeller 57 rotates, air is introduced into the first chamber 41a through the suction pipe 151 and the suction port 153 . The suction pipe 151 is provided with a guide 155 for allowing the air discharged from the suction port 153 to flow in a tangential direction to the circumferential surface of the first chamber 41a. Accordingly, the air introduced into the first chamber 41a will have a cyclonic flow along the circumferential surface of the first chamber 41a.

When air cyclone flows inside the first chamber 41a, the foreign material moves to the circumferential surface of the first chamber 41a by centrifugal force, and then the first cover 183 provided on the bottom surface of the first housing by gravity. ), and the air will be introduced into the second chamber 41b through the communication hole 414 .

The user can remove foreign substances accumulated in the second space 419 and the first chamber 41a by rotating the first cover 183 to open the lower through-hole 181 .

2 and 5, the straight line V2 passing through the center of gravity G2 of the fan 5 is based on the straight line V1 passing through the center of gravity G1 of the foreign material separation unit. Preferably, the handle 8 is inclined at an angle A greater than 0 degrees and less than 90 toward the direction in which the handle 8 is positioned. That is, the rotation shaft 545 is rotated at an angle A greater than 0 degrees and less than 90 degrees in the direction in which the handle 8 is positioned based on a straight line V1 passing through the center of gravity G1 of the foreign material separation unit. It is preferable to be provided inclinedly.

When the rotation shaft 545 is provided in a direction orthogonal to a straight line V1 passing through the center of gravity G1 of the foreign material separation unit 4, air is discharged toward the direction in which the handle 8 is located, so that the user Problems that cause discomfort to users and problems of spraying fine dust to users may occur.

On the other hand, when the foreign material separation unit 4 and the fan 5 are arranged vertically and the rotation shaft 545 is located on a straight line V1 passing through the center of gravity of the foreign material separation unit 4, the foreign material separation unit The center of gravity (G1) and the center of gravity (G2) of the fan are both located in front of the handle (8). When the center of gravity of the vacuum cleaner moves away from the handle 8, it means that the center of gravity of the vacuum cleaner is located farther from the user's wrist. The downside is that it requires power.

The angle A set to the rotation shaft 545 can solve both of these problems. That is, since the angle of the rotation shaft 545 is less than 90 degrees, air is not discharged in the direction in which the handle 8 is positioned.

In addition, since the center of gravity (G2) of the fan is close to the handle (8), the angle (A) of the rotation axis with respect to the straight line (V1) passing through the center of gravity of the foreign material separation unit is 0 degrees compared to the case of the cleaner (100) ) can move the entire center of gravity in the direction in which the handle 8 is located. Accordingly, the user can handle the cleaner 100 of the present invention with a relatively small force.

On the other hand, the angle at which the second housing 13 is inclined toward the handle with respect to a vertical line passing through the center of the first housing 11 is a straight line (V1) through which the rotation shaft 545 passes through the center of gravity of the foreign material separation unit. It is preferable to set the same as the angle (A) inclined with respect to the straight line orthogonal to the first cover.

However, it is preferable that the inclination angle A of the rotating shaft 545 with respect to the straight line V1 passing through the center of gravity of the foreign material separation unit is set to be 30 degrees or more and 60 degrees or less. When the inclination angle A is less than 30 degrees, it is difficult to expect a large difference from the conventional vacuum cleaner having an inclination angle of 0 degrees, and when the inclination angle A is 60 degrees or more, it is difficult to expect a large difference from the conventional vacuum cleaner having an inclination angle of 90 degrees.

5 illustrates an example in which the inclination angle A of the rotating shaft 545 is 45 degrees with respect to the straight line V1 passing through the center of gravity of the foreign material separation unit. According to the experiment, in this case, the burden on the handling of the cleaner felt by the user was evaluated to be the lowest.

As mentioned above, the motor 54 provided in the fan may receive power through the battery 7 detachably provided in the housing 1 . In this case, the battery housing 6 providing a space in which the battery 7 is accommodated should be provided on the circumferential surface of the first housing 11 .

The battery housing 6 provided in the present invention is a point (a point 180 degrees apart) located in the opposite direction to the point where the suction part 15 is located among the space provided by the circumferential surface of the first housing 11 . is located in In addition, the battery housing 6 is provided to protrude in a direction away from the circumferential surface of the first housing 11 .

The battery 7 may be detachably inserted into the battery housing 6 through an insertion hole 61 (refer to FIG. 1 ) provided to penetrate the bottom surface of the battery housing 6 or the side surface of the battery housing. .

In this case, one end of the handle 8 may be fixed to the circumferential surface of the second housing 13 , and the other end may be fixed to the upper surface of the battery housing 6 . That is, the handle 8 includes a bar-shaped handle body 81 extending from the battery housing 6 toward the second housing 13 , and attaching the handle body 81 to the second housing. It may include a bar-shaped connecting body 83 connected to the circumferential surface of (13).

The handle body 81 may be provided to have an inclination angle of 70 to 80 degrees with respect to the reference line L1 passing through the center of the suction part. 5 illustrates an example in which a straight line L2 passing through the center of the handle body 81 has an inclination angle of 75 degrees with respect to the reference line L1.

As the height of the battery housing 6 increases, the length of the handle body 81 becomes shorter, which may cause inconvenience to the user. The length of the battery 7 facing the direction (the length of the battery in the Y-axis direction) is the length of the battery 7 with respect to the height direction of the first housing 11 (the length of the battery in the Z-axis direction), and the first Preferably, the length of the battery in the radial direction of the housing 11 (the length of the battery in the X-axis direction) is set longer.

Further, the center of gravity (G2) of the fan is located between the center of gravity (G1) of the foreign material separation unit and the center of gravity (G3) of the battery, and the center of gravity (G3) of the battery is the center of gravity (G2) of the fan And it may be provided to be positioned between the center of gravity (G4) of the handle (8). By disposing each center of gravity (G1, G2, G3) close to the center of gravity (G4) of the handle, it is possible to handle the vacuum cleaner with a small force.

On the other hand, the center of gravity (G2) of the fan is located between the center of gravity (G1) of the foreign material separation unit and the center of gravity (G3) of the battery, and the center of gravity (G3) of the battery is the center of gravity (G2) of the fan and Even if it is located between the center of gravity (G4) of the handle, if the center of gravity (G1, G2, G3) of the fan, the foreign material separation unit and the battery are located on one straight line, the center of gravity of the cleaner will be farther from the handle (8). will be.

Accordingly, the center of gravity (G2) of the fan is located above the reference line (L1) passing through the center of the suction unit 15, and the center of gravity (G1) of the foreign material separation unit and the center of gravity (G3) of the battery are It is preferably located below the reference line L1 passing through the center of the suction part.

However, the center of gravity G4 of the handle may be located on the reference line L1 passing through the center of the suction unit, or may be located below the reference line L1 passing through the center of the suction unit.

In addition, as shown in FIG. 6 , the center of gravity of the fan (G2), the center of gravity (G1) of the foreign material separation unit, the center of gravity (G3) of the battery, and the center of gravity (G4) of the handle are single plane It is preferable to be provided in (the cross section in the height direction of the vacuum cleaner). That is, the center of gravity (G2) of the fan, the center of gravity (G1) of the foreign material separation unit, the center of gravity (G3) of the battery, and the center of gravity (G4) of the handle include a straight line passing through the center of the suction unit Preferably, they are all located on a single vertical plane. This is because it is more advantageous for handling of the cleaner that the centers of gravity (G1, G2, G3, G4) of each component are all located on the cross section in the height direction (Z-axis direction) of the cleaner.
